Abstract
An electric double layer capacitor has high static capacitance, and superior durability, and the amount of gas generated by dissociating solvent can be reduced. In an electric double layer capacitor including an anode and a cathode containing active carbon, a separator, and nonaqueous electrolyte solution, the crystallite thickness Lc(002) of the d002 plane of the active carbon used for the anode is set to be larger than the crystallite thickness Lc(002) of the d002 plane of the active carbon used for the cathode.
Claims5
An electric double layer capacitor comprising an anode and a cathode comprising active carbon, a separator, and nonaqueous electrolyte solution as a solvent, wherein crystallite thickness Lc(002) of a d002 plane of the active carbon used for the anode is larger than the crystallite thickness Lc(002) of the d002 plane of the active carbon used for the cathode.
